Original, and sound wave will not influence other people because of spreading in air.Nowadays the use of bone conduction earphone is more and more wider
It is general.
However, driving air vibration to generate sound, osteoacusis vibrating speaker by vibrating diaphragm relative to gas conduction speaker
The soft tissue and bone for needing to drive user vibrate, thus its required mechanical output is higher.It is passed to improve bone
Lead the mechanical output of loudspeaker.Chinese patent literature CN201820027238.7 discloses a kind of magnetic circuit group of bone-conduction speaker
Part.The magnet assembly generates the first full field, and the magnetic circuit component includes the first magnetic element, the first magnetic conductive component and second
Magnetic conductive component.First magnetic element generates the second magnetic field.Second magnetic conductive component surround first magnetic element, and
Magnetic gap is formed between first magnetic element.The magnetic circuit component further includes at least one second magnetic element.It is described
At least one the second magnetic element is placed in the lower section of the magnetic gap, and magnetic field of first full field in the magnetic gap is strong
Degree is greater than magnetic field strength of second magnetic field in the magnetic gap.The patent document increases magnetic by increasing magnetic element
The mechanical output of field intensity raising bone-conduction speaker.
However, necessarily will increase the overall weight and volume of loudspeaker due to increasing magnetic element, can not substantially increase
Add the sensitivity of entire loudspeaker and reduce small product size, and production technology is complicated, fraction defective is high, and product service life can not
It leans on.
